secure login: user_isloggedin() problem

CaptainAwesome

Hi there,

I'm trying to implement the secure user login system, and I'm immediately having problems with the 'Call to undefined function: user_isloggedin()' error.
The code I'm using is as follows..

<?php

include($DOCUMENT_ROOT.'/include/database.php');
include($DOCUMENT_ROOT.'/include/pre.php');
include($DOCUMENT_ROOT.'/include/user.php');

if (user_isloggedin()) {
        user_logout();
        $user_name='';
}

if ($submit) {
	user_login($user_name,$password);
}

site_header('Login To PHPBuilder');

if ($feedback) {
	echo '<FONT COLOR="RED"><H2>'.$feedback.'</H2></FONT>';
}

echo '<H3>Login To ServerServer.ca</H3>
	<P>
	Enter your user name and password and we\'ll set a cookie so we know you\'re logged in.
	<P>
	<FORM ACTION="'. $PHP_SELF .'" METHOD="POST">
	<B>User Name:</B><BR>
	<INPUT TYPE="TEXT" NAME="user_name" VALUE="" SIZE="10" MAXLENGTH="15">
	<P>
	<B>Password:</B><BR>
	<INPUT TYPE="password" NAME="password" VALUE="" SIZE="10" MAXLENGTH="15">
	<P>
	<INPUT TYPE="SUBMIT" NAME="submit" VALUE="Login To PHPBuilder">
	</FORM>
	<P>
	<A HREF="register.php">[ Register A New Account ]</A>
	<P>
	<A HREF="changepass.php">[ Change Your Password ]</A>
	<P>
	<A HREF="changeemail.php">[ Change Your Email Address ]</A>';

site_footer();

?>

anyone know a way out from this?

Either (a) you have spelled the function name wrong, (b) the file it is defined in has not been successfully included (I'd suggest you use require() instead of include(), then), (c) you have forgotten to include (require) the file that defines that function, (d) there is no such function and somebody/something has confused you. 😉

You might want to start by adding an error_reporting(E_ALL); at the beginning of the script to see if any additional information is available from the PHP processor.

You are not trying to write a login to this site: phpbuilder.com

site_header('Login To PHPBuilder');

include($DOCUMENT_ROOT.'/include/database.php');

Correct me if I'm wrong, someone, but shouldn't that be $_SERVER['DOCUMENT_ROOT']? register_globals could be off, preventing his includes from working?

Even better - register_globals should be off!
